Take the LHCb Virtual Tour

The LHCb detector in the experimental hall located 90 meters below the surface. To the right is visible the transfer tunnel with the 10 meter diameter shaft linking the underground area to the surface hall above. On the backside the shielding wall (built of concrete blocks, 3.2 m thick) and in the corner the so-called chicane which allows persons passing between the accessible part of the hall behind the shielding wall and the experimental hall.

View into the dipole magnet with the Beryllium beam pipe. In the background the Inner Tracker (metallic boxes) and Outer Tracker (long vertical black modules). On the left: The Trigger Tracker station, the RICH-1 detector and the Vertex Locator, hidden behind cables. In the background of the Vertex Locator the shielding wall separating the cavern from the LHC machine tunnel. Further to the left, behind the fence the cryogenics plant for the LHC machine.

The Muon detection system is hidden behind the tower filled with electronics racks to read out the 200,000 signal channels. To the left of it the backside of the calorimeter system (in an opened position), further to the left a view on to the cryogenics equipment for the LHC machine, the large pipe in the foreground brings the cold Helium to the 220 magnets in one of the eight 3.2 km long sectors to ‑271°C.

In the LHC tunnel near LHCb: the red objects are the so-called final focus magnets that are squeezing the proton beam to its very small size (~human hair) in the interaction region of LHCb just behind the wall in the background, turning right the bypass tunnel with its shielding (open); further turning to the right a view into the so-called straight section of the LHC tunnel.

In the LHC tunnel near LHCb: in the foreground, a so-called feed box that feeds the magnets in the tunnel with currents up to 12000 Amperes; to the left a view into the arc of the LHC tunnel with the superconducting magnets, the next point of access is 3.2 km away!
